Specification of LettersPatent I I Patented Jan. 21, 1908.

Application filed Ja ua y 14,1907. are No. 352.242.

syl ania, have invented certain new and useful' mprovements in Conveyers, of which the following is a specification, reference being had therein to the accompanying drawing.

. Our invention refers to improvements in conveyors and is particularly designed as a coke conveyer for the purpose 'of transporting'coke from an oven door to any desired point of discharge, for depositing it into cars or elsewhere. I

The invention is intended to be used in conjunction with any suitable coke drawing apparatus, as for instance the machine shown and described in our prior a plication filed Dec. 21st,1906 bearing the erial Number 348,896, and to receive the coke as drawn, convey it laterally along in front of the oven and then outwardly at any desired'an le tothe ovens or to the original line of trave and at any suitable-angle of elevation, to the point of discharge.

Generally stated, the conveyor consists of a continuous series of flights and universally connected or jointed carrying means arranged to travel along a trough mounted upon a suitable framework having supporting, driving and adjusting mechanism, and adapted to operate in the manner hereinafter described.'

Referring to the drawings: Fi ure 1 is a general plan view, partly bro en away, showing the conveyor located in position for operation with relation to the oven and in conjunction with a drawing machine.

The ap aratus comprises generally atruck C and t e conveymg mechanism carried thereby, mounted upon tracks 2, '2, extend.,

ing along in front of a bank of coke ovens, or in operative relation to any other structure with which the oonveyer is desired to be used.

The convey'er truck C as shown in Fig. 1, is

coupled with acoke drawing ap aratus comprising a truck A and adjustable carrier B provided with an extractor, similar to the machine shown in our prior application above referred to, but may be used 'in conjunction. with any other type of drawing machine or independeiitly as desired. The conv'eyer truck is provided with a motor 3 of any suitable type, as as: electric motor, from which the power is taken for ropelling the apparatus along the tracks an also for operating the conveyor, although separate motors may be employed for each service if preferred. The truck C is preferably construoted of structural steel, comprising aframework composed of side and end sills 4 and 5 of channel or other suitable form,'properly braced, mounted by suitable bearings on axles 6 havin supporting wheels 7, 8, running on trac s 2. As shown, the inner wheels 7 are quite broad and flat'across the tread, merely resting on the topof the inner.

troughs, or

. flanges reversed downwardly as shown intion independent of any variations in paraldiate curved sectionsc -on horizontal or in various supporting and driving sprocket .nel or other suitable form which are station vary throughout the main portion of the conflights of the conveyer travel, and upon thereby.

' carrying chains traveling in a direction rail, while the outer wheels 8 are heavily flanged'at each side so as to embrace the head of the rail and brace the carriageagainst strains in either direction, and insure traclelism of the rails.

9 is an upper structural framework properly designed to support the conveyer and provided with an upwardly extending tower 10 for counterbalanoing and adjustln the delivery end of the conveyer as clearly s 'own in F g. 6. The conveyer properismounted upon said framework and consists generally 0 one continuous carrying chain of-the f end less sprocket type, provided with laterally" arranged flights, disposed in upper and lower oppositely traveling series, in two main portions, *5. e. a receiving portion or leg 0 and a delivery portionor leg c'.' The conveyeris designed with such a degree of universal flexibility that it will pass through intermeclined planes and will .also pass around the wheels in different planes, so as to traverse the whole distance from the receiving point :to-the delivery point by means'of one continuous flexible carrying structure.

The entire lower series of flights and their carrying chains traveling in a direction away from the oven door or from any receiving point, are supported upon a run-way consisting of main side members 11, 12, of chanveyer including the section 0 and c to the point where the delivery section c is hinged, 1 as shown in Fig. 6 j while the same elements 11; 12, constitute the'supporting members of the lower run-Way of the delivery section. Each of said sections'is provided with a flat supporting bottom 3 and 13 respectively of plate metal secured underneath to the flanges of members 11 and 12, as shown on Sheet 4 of the drawings. Said plate constitutes the bottom over which the which the coke or other material is carried The entire upper series of flights and their toward the oven door or away from the delive point, are likewise mounted and car- .ried iiy similar main elements as channels 14, 15, for main sections 0 and c and 14 and 15 for section 0 respectively. I

Each of said supporting members 11 and 14, for the outer ends of the flights, are provided along their upper edges with slideways, uides 16 of channel form, while similar ing channels -17 having their Fig. 1 2, are mounted above said channels 16 clearlyshown on sheet 7 of the drawing and as hereinafter described.

more clearly I- the teeth of the sprocket wheels.

:of the lower member 11 by brackets 18, whereby a confining guiding shdeway is pro- 1 vided for the. terminal shoesof the flights along the lower or load carryingrunway.

Supporting members 12 and 15 are likewise provided along their upper edgesv with similar slideways .19 of channel form, but open at the top' as is also channel 16 of upper member 14.as clearly shown, for engaging and supporting the sliding shoes of the flights and of the carrying chain. These guiding elements extend continuously along the main.

supporting members of the conveyer supporting structure, means for connecting them at the hinge juncture being provided as At the receiving end it, will be observed that the lower members 11 and 12 are located ata suitable distancebelow the oven door,

(shown in dotted lines in Fig. 4,) to receive .the contents of the oven as drawn, while the upper supporting members 14, 1 5, are located sufficiently high above the top of the door to give ample clearance for the extracting element of the drawing machine, said parts of the conveyer beingconnected at their outer ends by means of vertical posts 20 as shown.

At the outer or delivery end of the conveyer the driving s rocket wheel 22is mounted in .suitable bearings, the lowerand upper sup porting elements 11, 12,- and 14, 15, being rought into close parallel relationw'ith each other asshownin Fig. 6, soas to facilitate the travel of the chain with relation to its driving sprocket 22. The chain carrying the flights throughout the conveyer trough or runways is single longitudinally as shown,- andv is composed of universally flejrible elements consisting of links pivoted together in different planes alternately, referably at right angles to each other, as 0 early shown v in detail on Sheet 4.

23, 23, .are ordinary flat links pivoted at each end to link sections 24,24, and pro viding between them .the' usual space for Links 7 24 connected by pin 25 carrying roller 26, connect adjacent pairs of links 23 as shown, while the alternating rollers 26 of the chain are mounted in similar links 24 one of said links 24 however being ofspecial form for the purpose of attaching the flight. Said link is provided with a laterally extending bracket 27 at its inner side, and at the oppotions and'provided with the alternate differently'hingedpivotal l'ieznings, is flexible in both directions, i. c. vertically and horizontally, so that it will freely pass around and travel in the various directions above noted, and will be at the same time positivel y guided and supported by shoes 29 in their appropriate guiding runways 1.9, of, the lower and upper members 12 and 15.

3lis the flight, of channel or other suitable form, attached by bolts 32- as shown to bracketZ? of each special link 24 which links are located a suitable distance apart to suit the requirements of the apparatus and admit of the coke in front or" the flights: The flights 31 extend substantially across the area of the runway or trough, resting ,upon or preferably immediately above the floor plate 1.3, and are provided at their outer ends with brackets 33 extending upwardly and outwardly and having terminal shoes 34 similar to shoes 29, or other suitable guiding devices, mounted between the lower and upper guiding channels 16, 17, and adapted to travel through and be guided thereby. The shape of shoes 29 and is clearly shown in Fig. 13, giving suflicient lower and upper bearing and having rounded corners so as to pass l'reel y along the guidin channels. By means of said shoes it wil be seen that the flights are supported, any-tendency to disarrangement of the flightsv or torsion of the chain is avoided, and the entire structure is suitably braced against the various strains to which it is subjected in use. 1

Rollers 26 bearing against the inner channels .12 and being located in central alinement with the chain, provide rolling bearings, thereby Facilitating the continuous easy travel of the structure.

YVhen the conveyer is carrying a load, in front of each flight 31, the backward tendency of each flight is counteracted by and itself counteracts the tendency of its adjacent flights to deflect from the right angular arrangement with relation 'to the carrying chain. This is due to the. fact that each flight and its links 23 and 24 constitutes a practically still bracket as to lateral move ment up to the point where it is pivotally connected to the adjacent bracket by roller pin 25. The opposin strains under load are thus centralized an neutralized at each roller bearing.

The receiving end of the supporting structure is hung. from the top of tower by means of one or more supporting rods or tension members '35, preferably provided with turnbuckles 36 for adjustment, while such end of the apparatus 1s likewise supported upon alaterally extending arm 49 mounted upon and projecting from the extracting apparatus, as has been described in our prior application above referred to. On

I veyer or section 0 is supported by means of cables 37 passing around sheaves 38 and 39 at the top of the mast 10 and outer end of the conveyer section respectively, as clearly Sl'lOWl'l in Fig. 6, the free end of the cable passing downwardly to a suitable winch 40 adapted to be turned by the operator through suitable gearing and shaft 41, provided with a hand. wheel 42. By such means the delivery end of the conveyer may be raised or lowered to the desired height and there mainof adjustment within a sufficient degree to provide ior dehvering-coke either into open 43 is a delivery chute or spout, as clearly shown on Sheet 3, rotatively mounted by means of rollers or wheels 44 upon a lower flange 45 of an upper section 46, mounted for longitudinal adjustment underneath the delivery conveyer section 0. The bottom plate 13 of the delivery section of the conopenings 47 and corresponding opening and mounted in slideways or otherwise as desired, and said openings may be of any number preferred as shown in Fig. 7. The upper section 46 of the delivery chute is mounted for longitudinal travel along the lower side of rollers or wheels 50 engaging the lower flanges of the main structural members 11, 12 and sup orting by brackets 51 the section 46. ny other suitable supporting flanges may be substituted for said flanges. For the purpose of adjusting said section, together with the suspended terminal spout 43, sections-46 are provided at front and back with suitable connections 52, 52, to which are attached the cables or other flexi ble conductors 53, 53, the front one of said cables passing around suitable guiding sheaves 54, 54.. and both cables passing backwardly, around sheaves 55 and to a winch 56 operated by worm gearing 57 or other suitwith a hand wheel 58, .as clearly shown in Fig. 6. By such means, the delivery chute may be located underneath either one of the closed by their doors, so that the coke as conveyed outwardly along the bottom plate 13 of the conveyer will be discharged downwardly through opening 47 section 46, and spout 43 intothe car ,-.or laterally to any point desired, depending upon the angle at which the spout 43 is turned, as suggested by the dotted lines of Fig. 7. 7

While separate motors may be employed to impart traction power to the axles of wheels 7 and 8 and also to actuate the conveying mechanism, I have utilized a single motor 3, from which by gearing 59 and 60 tained, it being understood that it is capable top or box cars, or elsewhere upon the yard.

closing gates 48 which may be conveniently able means from an operating shaft provided veyer'is provided with one or more outlet of the delivery end of the conveyer by means several openings 47, the other openings being 1 the other hand; the delivery end of the con- 1 power is imparted either to shaft 61 and v outer ends ofsliding frames 78,v 79,, preferworms 6 2, 62, engaging worm wheels 63, 63,

mounted'on the axles to rotate them; or to sprocket wheel 64' to'drive chain 65 and wheel 64, to drive the through suitable countershaft and reducing sprockets located adjacent to the'hinge connection of the upper delivery section of the conveyer,

chain 67, as clearly shown in Figs-1 and 6.

Driven gear wheel 60 is connected'at each narily, propelling power 1s intermittently imparted to the axles, while the conveyer is,

preferably driven continuously during serv- 1n order to positively prevent reverse rotation of the head shaft 71 carrying the conveyer chain head sprocket 22, the driving.

sprocket 66 may be loosely mounted on shaft 71, as clearly shown in Figs. 2 and 3 and adapted to drive said shaft in the proper direction, only, as indicated by the arrow, by

spring-pressed awls 72 engaging the teeth of a ratchet whee 73, keyed to shaft 71. By

this construction, should reverse motion bethe delivery frames 7 S and imparted to sprocket 66, it'will have no effect whatever upon the conveyer, thereby absolutely preventing reverse motion.

In Figs. 14, 15 and 16.1 have shown in detail a construetion whereby any slack of the chain, due to wear or vertical adjustment of I end of ltheconveyer, may be automatically taken'up'. In such construction the lower i ler sprocket wheel- 21 is mounted in stationary bearings 74 which may befadjustably set outwardlyfrom time to time in an extension 75 on the lower framework and secured thereon by means of bolts and the supplemental bolt holes 76. as shown, while the u per idlersprocket 21 is mounted lD-SlIHllaI bearings 77 carried on the ably of tubular form as shown, passing backwardly through suitable guides 80, 81., of the upper framework and at each side thereof, as

shown in Fig. 16. I

82 is a coiled compression'spring inserted between rear bearing 81 and a collar 83 ct frame 78, by which the entire sprocket-carry: ing framework, connected by a diagonal cross brac 84, will be, automatically projected forwardly as indicated in dotted lines in Fig. 14, to take up the slack. The guiding 79 are 01'' suiflcient length to insure ample expansion, and it will be understood that should the stretch or slack of the chain at any time become excessive, it can be compensated 'for either by removing a section of the convcyer or a suitable number of links, or by setting the bearing 74 outwardly, as will be readily understood.

to finally drive sprocket 66 through For the purpose of providing continuous runways for the shoes of the flights, vertical guides 84, preferably of channel form, are pivoted at 85 at the upper portion of curve continuations 86 of the horizontal guide ways, being provided at their upper ends with similar curved continuations 87, for the same purpose. By this construction it will be seen that continuous slideways for the conveyer flights will be provided without interruption. For the purpose of similarly providing con tinuous slide-ways at the pivoted juncture of the stationary and movable sections of the main conveying frame, the outer section 0 is pivotally'mounted on cross shaft 88 as shown in Fig. 18. The lower and upper side members 11 and 14 are rigidly connected by a transverse bar 89 at each side of the 'con- .veyer, provided at their lower extremities with bearings 90 engaging shaft 88,jwhich in turn-is mounted -in suitable bearings carried by the main structural framework.

When the delivery end of the conveyer is in erected position, (shown in Fig. 6) the separate guide-waysfor shoes 29 and 34 are in alinement, the adjacent ends of upper channels 17 being flared upwardly as shown in Fig.'18 to insure easy travel from one to the other, while" the side flan es of lower channels 16 and 19 are deflected laterally at the entering side as indicated at 91 for the same purpose. Likewise the bottom portion of the stationery slideway extends orlaps over beyond the movable portion as indicated at 92, Fig. 21, thereby shoes on to the adjustable'gu1de-way of the. conveyer at any osition thereof. In the same manner the ottom portion of the up per channels 16 and 19 lap over onto the corresponding stationary channel as indicated 20, the side flanges of said staat ea'Fi tionary channel being flared outwardly as shown at 94 for the'purpose of facilitating entrance of the shoe., By this construction, as the adjustable terminal of the conveyer is set-in diiierent positions, the operation of the conveyor will be facilitated, at all times insuring continuous uninterrupted service.

In Fig. 22L have shown a construction of conveyer trough provided with screen bars insuring passage of the p 95 arranged along the bottom instead of the bottom plate, between the side members 11 and 12 and resting on suitable cross supports 96 in the manner .well understood in conveyer ractice. It will be seen that any por-- tion 0 the conveyer trough may be provided with such screen bars or equivalent screening bottom so as to screen the small coke as the charge is conveyed along.

' The operation of the invention will be readily understood from the foregoing description. It provides a continuous conveyer adapted to pass around corners or to traverse various planes without the necessity of any supplemental or auxiliary conveying mechanism, and in. this respect constitutes an important advance in the conveying art. The invention may be variously changed or modified to suit local conditions of use; the a paratus may be designed for otheruses tnan the particular one herein described, and may be 'utiii /ed for various purposes or adaptations to convey material in other than 1 straight lines, and will be found to be of. great advantage in many dil'i'erent applications.
